The Week That Was: Audi A4, Fiat 500, Lamborghini Aventador SV Roadster

Audi has lifted the lid on its all-new A4, which is due to arrive in Australia in the first half of next year to do battle with the ever-popular C-Class, the BMW 3 Series and Lexus IS.

Full details will be revealed at the new A4's first public appearance at the Frankfurt Motor Show in September.

For now, Audi has trickled out a few snippets about the 2016 A4's new lightweight architecture, engine line-up and bold interior design.

Measuring 4.73 metres long, 1.82 metres wide and sitting on a 2.82 metre wheelbase in sedan form, the new A4 is longer and wider than the current model. However, thanks to a range of lightweight construction measures, it will be up to 120kg lighter.

Fiat has unveiled its updated 500 hatch for 2015, bringing refreshed styling and new interior tech to the popular city car.

The Italian carmaker chose July 4 to officially pull the covers from its latest 500 model, being the anniversary date of the ‘original 500’ in 1957 and the modern-day version in 2007 - the latter about to enter its eight year of production.

The 2015 500 brings 1800 changes to the outgoing model, according to Fiat, the most significant of which is a central infotainment screen for the interior.
